What reviewers found
Roborock Saros 10R
- BGR: Called it Roborock's best model at launch. It fit under sofas and beds, had about 57% battery left after about 80 minutes of vacuuming and mopping, and needed tank service every four to six cleanings. It tangled in cables until a no go zone was set. Source
- TechRadar: Noise measured 62 dB at source and 55 dB at 10 feet. Oats were cleared but flour stayed in floor seams on Max and Max+. It cleaned a syrup, soy sauce and milk spill in one pass on low water and mapped five areas in about 5 min. It rode over a 1 inch dog bone until Pet mode was turned on, and the dust bag filled in about three weeks. Source
Roborock Saros 20 Flow
- House Digest (9/10): Floors came out about 90% clean with some crumbs left in corners. Mopping fully removed ketchup and barbecue sauce and left wood almost dry. It cleared a baby gate but got lost once and had underwhelming edge cleaning. Source
- EFTM (92%): Australian review gave vacuuming 93%, mopping 93%, app 92% and features 93%. It cleaned dried jam and tomato sauce, needed two passes for Vegemite and struggled with crumbs near cabinets. Charging was slow. Source
